Modifiable lifestyle behaviors are important factors for improving mental health, yet there has been a lack of research studying lifestyle as a multidimensional construct in bipolar disorder (BD). The aim of this cross-sectional study was to compare the lifestyle patterns of individuals with BD in a current mood episode with healthy controls (HCs) using the Short Multidimensional Inventory Lifestyle Evaluation (SMILE).
The sample consisted of 46 individuals with BD currently experiencing a depressive or manic episode and 50 HC, assessed using the MINI International Neuropsychiatric Interview, Montgomery-Åsberg Depression Rating Scale (MADRS), and the Young Mania Rating Scale (YMRS). The SMILE scale assesses lifestyle across seven domains: diet and nutrition, substance abuse, physical activity, stress management, restorative sleep, social support, and environmental exposures. Between-groups comparisons were performed based on the presence of a psychiatric diagnosis and the type of BD episode.
We found significant differences in the total SMILE score (r=0.75, p<0.001) and in scores from each domain of the scale between BD and HC (p<0.05), where individuals with BD in a depressive or manic episode with or without mixed features reported worse lifestyle across all domains. Differences between individuals with BD in different mood episodes across domains on the SMILE scale were non-significant.
Findings from this study highlight the presence of unhealthy lifestyle patterns in people with BD regardless of the polarity of their mood episode. Implementation of multidimensional lifestyle assessments is an essential step toward detecting the clustering of unhealthy lifestyle patterns in BD.
可改变的生活方式行为是改善心理健康的重要因素，但在双相情感障碍（BD）中，针对生活方式作为多维结构的研究较少。本横断面研究的目的是使用短期多维生活方式评估量表（SMILE）比较处于当前心境发作期的 BD 患者和健康对照（HC）的生活方式模式。
该样本包括 46 名目前处于抑郁或躁狂发作期的 BD 患者和 50 名 HC，使用 MINI 国际神经精神访谈、蒙哥马利-Åsberg 抑郁评定量表（MADRS）和 Young 躁狂评定量表（YMRS）进行评估。SMILE 量表评估七个领域的生活方式：饮食和营养、物质滥用、身体活动、压力管理、恢复性睡眠、社会支持和环境暴露。根据是否存在精神诊断和 BD 发作类型进行组间比较。
我们发现 SMILE 总分（r=0.75，p<0.001）和各领域得分存在显著差异（p<0.05），处于抑郁或躁狂发作期且伴有或不伴有混合特征的 BD 患者在所有领域的生活方式均较差。SMILE 量表上不同心境发作期的 BD 患者在各领域的差异无统计学意义。
本研究结果强调了 BD 患者无论心境发作的极性如何，都存在不健康的生活方式模式。实施多维生活方式评估是检测 BD 中不健康生活方式模式聚类的重要步骤。
